Django提交表单POST无效

Question

我正在尝试提交一个表单来填充数据库。我不能使邮政工作。它看起来不正确，但我不知道该怎么做才能纠正它。

我已经进行了一些调试，看看当我点击提交&POST被发送。我不知道如何发送created_at或created_by。我认为这就是POST无效和数据库未填充的原因。

models.py

from django.db import models
from django.contrib.auth.models import User
from django.forms import ModelForm
class Order(models.Model):
order_name = models.CharField(max_length=100, unique=True, null=True, blank=True)
created_at = models.DateTimeField(auto_now_add=True)
created_by = models.ForeignKey(User, related_name='Project_created_by', on_delete=models.DO_NOTHING)
def __str__(self):
return self.order_name
class Ce_Base(models.Model):
ce_hostname = models.CharField(max_length=15)
new = models.BooleanField()
location = models.TextField()
order_reference = models.ManyToManyField(Order)

forms.py

from django.forms import ModelForm
from .models import Order
class OrderForm(ModelForm):
class Meta:
model = Order
fields = ['order_name']

views.py

from django.shortcuts import render
from django.contrib.auth.decorators import login_required
from .models import Order
from .models import Ce_Base
from .forms import OrderForm
@login_required
def home(request):
form = OrderForm()
if request.method == 'POST':
form = OrderForm()
form.instance.created_by = request.user
print(request.POST)
if form.is_valid():
form.save()
context = {
'order': Order.objects.all(),
'form': form,
}
return render(request, 'orchestration/order_create.html', context)
@login_required
def orderprocessing(request):
context = {
'ce_base': Ce_Base.objects.all()
}
return render(request, 'orchestration/order_processing.html', context)

html

{% extends "orchestration/base.html" %}
{% block content %}
<h1>Input Form</h1>
<form action="" method="post">
{% csrf_token %}
{{ form }}
<input type="submit" >
</form>
<h1>Orders</h1>
{% for each_order in order %}
<p>Order Name: {{ each_order.order_name }}</p>
<p>Created On: {{ each_order.created_at }}</p>
<p>Created By: {{ each_order.created_by }}</p>
{% endfor %}
{% endblock content %}

这是我点击提交按钮时的终端输出

如果表单中没有传递数据，则验证失败。

form = OrderForm(request.POST)
